reatment of colonic cancer (CC) and synchronic liver metastasis (SLM) is still controversial in relation to how to act. The aim of this study was to analyze initial single center experience in simultaneous surgical approach of patients with CC and SLM, in terms of overall survival (OS) and disease-free survival (DFS). Retrospective case series of patients with CC and SLM undergoing simultaneous surgery, consecutively, at Clínica RedSalud Mayor Temuco, between 2007 and 2021. Outcome variables were OS and DFS. Other variables of interest were postoperative morbidity (POM), surgical time, hospital stay and mortality. Descriptive statistics was used (measures of central tendency and dispersion), and survival analysis was estimated applying Kaplan Meier curves. Sixteen patients (10 female and 6 male) were operated, with a median age of 61 years. The most frequent localization was cecum and right colon (37.5 %). In all patients some type of liver resection was added (parenchymal-sparing hepatectomy or anatomical resection). Median surgical time and hospital stay were 150 min and 5 days respectively. POM was 31.2 % (5 cases), mainly Clavien & Dindo I and II (12.5 % of patients required a re-intervention). With a median follow-up of 52 months 1, 3 and 5-year OS were 100 %, 62.5 %, and 50.0 % respectively. On the other hand, DFS rates of 1, 3 and 5-year were 75.0 %, 43.8 %, and 25.0 % respectively. The series had no mortality. OS, DFS, POM and mortality, were like other series. Simultaneous resection of CC and SLM is an aggressive approach, but not compromise oncological outcomes.
